To alltchom inn my concern.-

a Be it known that I, EDMOND nvY sn r oa,

of the city of Paris, France, have invented a Continuously Acting Centrifugal Machine, (for which I have obtained Letters Patent in France for fifteen years, dated February 12,

1892, No. 219,358; in Germany for fifteen 1gium for fifteen years,dated August 1,1892,

.No 100,772, and in'Austria-Hungary, dated March 28, 1893, No. 39,858 and No. 86,589,) of 1 which the followingis a full, clear, and exact description. 1 1

This invention relates to a continuouslyacting centrifugal machine or hydroero; tractor, more especially intended for use in sugar manufacturebut applicableto other purposes by modifications in detail which in nojwayafiect the principle of the invention.

Reference isto be had to the accompanying 1 drawings, forming part of this specification, which illustrate the machineas arranged for 1 the specialpurpose indicated, wherein- Figurelrepresents a central vertical sec tion of the centrifugal machine, and Fig. 2 a horizontal section ofthe same on the line 1-2 Fig. 1. Fig. 3 is a perspective View, and Fig} 1 4 a vertical section of the distributor.

The same letters of reference denote like parts in all the figures.

The machine comprises a slightlyconed outer revolving drum 0. closed by atop cover i b and a bottom a and is provided Withintere nal vertical ribs d forming a seriesof cham i 35.

a 1 liquids drained off. Each of these chambers bers e e e c (Fig. 2) for the assortment of the has an outlet pipe e 6 (Fig. 1) leading to one of the series of collecting channels f f f f 3 in the lower part of the outerstationarycasing A, the two diametrically opposite chambers communicating with the same channel.

Thecover b is annular and carries a central distributor which revolves with the drum a and which distributes the matter to be treated and the washing or other medium with which i it is treated. i The distributer is a cylinder 71 p closed by abottom h and provided with internal horizontal dividing ledges h! h h forming a series of circumferential channels 70 into the three uppermost of which project stationary'nozzlesl to Z by which steam or other washing medium is supplied. Pairs of diametricallyopposite ports is? to [a open from the respective "channels Ycthrough the side of the distributerrleach pair of ports being situtheports above or below whereby the washing or ether'media are distributed at predeterm d rqi are closed at their outer ends bydoors n of perforated metal or wire gauze. This inner chambered drum is mounted upon a shaft 0 difierent'speed. Each perforated door n of the chambered drum is pivoted on a central vertical axis a. so as to be balanced and is provided ,with curved arms n which bear partitions d of the outer revolving-chambered drum 0. whereby the doors are held in the closed position. The drum a has two crystals, or other solid matters,.may be discharged into the space f withinthe upper partof the outer casing which may be lined with fabric to prevent the crystals being incasing. 1

The [means whereby each palr of doors at is opened on coming opposite the apertures atedin adiiferent yertical plane to those of y Theouter drum (1 and distributor tare car T distributor 11 and forming chambers which 1 7s 1 passing through the hollow shaft m and re: volving independently thereof at a slightly 1 against circumferential rails d fixed to the diametrically opposite outlet apertures at (Fig. 2) in its side,through which the sugar jured by striking against the walls of the" in the outer drum are illustrated in Fig.2

A fork 1c ;c -at {the upper end of the door-axis engages a stud d on the cover plateb which, by the relative motion in the direction of the arrow, gradually opens the door at the proper moment, the stud d becoming disengaged from the fork c c by the continued 'motion,i whereupon the door is closed by coming against the rails d. The door can only be opened in one direction, the fork preventing the opening in the opposite direction under' the action of centrifugal force, and the action of this mechanismis-dependent uponthe difg ferentialmotion of the inner and outer drums B anda.

The operation of themac'hine is essentially as follows, whatever the material operated v 7 upon: The inner-chambered drum Brevolvesat a speed dilteringfromthatof the outer drum ato the ex't'ent of 'one or2more'revolu-. 'tions per minute according to requirements, so that the charge to be treatedjfed "to the distributer by pipe l "and delivered through 1 the .pair of ports k"is'projeote'd, as "indicated by theiarrow "1 in Fig. 2,'into the two'opposite chambers marked 11) whichfor the time 'Ibeingcoincidewith thesaidports k". "Owing to the difierence of velocity of theinn'er and outer drums, these two chambers pass-aheadE or lag behindlthe point'in dicated'by thearrow and-are replaced'by theadj acen't'pairoftcham- "hers formed between the "partitions nwhich come oppositethe portslc' in turn,forthe;purl .pose of receivinga charge. The charge thus projected into chambers e isthrown by centrifugal action againstithe peripheral doors,; 7 the-solid particles are retained by the wire cloth, and the liquid is received in the 'corre-j sponding compartments act the outer drum a and flows 'throughithe delivery pipe e into the corresponding collecting channel jiin'theil casing. The chambers u retaining the "solid mattersthen come opposite the pairof portsf 10 through which is projectedzthe fluid em- ,ployed for thepreliminarytreatment supplied 'j 5 by the pipe Z, the liquid drained off passing; tintoits corresponding compartments cgand flowing out into "the corresponding channel L f Similarly, the said chambers coincide successively with the pairs of ports "k and'k 1 and .receiveo'ther fluids by which the'treatment of the solid matters is completed the ilGSliltil] g "liquids jbeing'received'in the 'corre- 1 .spondin'g compartments e e and .collectedin L the respectively corresponding channels f f3. "The chambers then *come opposite the, outlets or, of the drum a, 'thefork c" '0 on the door pivot engages with 'thestud bEwhi'ch'is vsituated oppositeithe center of the opening, oi, and the door isgradually openedto allow the solid mattersfto be discharged into "the chamber 1. The fork c"is'then'released'by the continued rotation'and the door is closed 7 by coming against the rails d. "Theactionis similar for each succeeding group of'two dia- I metrically opposite chambers, from their pas- 5 "isillustratedinthedrawings,which,however,

forms no part of my present'invention. In this example the shaftm is driven by a belt on pulley p and has keyed'on it a disk q provided with lug'sq' g in WIiichdsjournaIeda worm r ingear with -a 3 wormwheel f' keyed 1 on the shaft oby' which thecham'bered I drum is revolved. Upon each-end "of theshaft of the worm r is keyed-a ratchetwheel r with'whi'ch engagesapawl'r carried by-a lever s oscillati-ng ab'out the'shaft of the worm 1'. Each 7 ratchet "wheel 4 may be provided with a check *pawl'a. Thetwo recklevers s-are con- 'nected by'a rod '8' coupled at itsrmiddle bya ba ll'and'socket joint withtheend (of arod 8 connected to the strap tJo'f a stationary eccentric t which is adjustable in -guides t upon the base plate-of the casin'g by turning the hand wheel "of screw By'this combination the worm a" is rotated on its own axis by'therevolutionof' thedisk g and consequently produces 'adilferential-movement 'of the wheel r and shaft '0, proportional to the eccentricity of the-eccentric t.
